.30 Super Fl. H&H

The .30 Super Flanged H&H, often referred to as the .30 Super Fl. H&H, is a classic British cartridge with roots dating back to the early 20th century. It was introduced by the renowned firm Holland & Holland as the flanged, or rimmed, version of their celebrated .30 Super Magnum cartridge (sometimes known as the .30 Belted Rimless H&H). Originally designed for break-action double rifles, this cartridge found favor among sportsmen seeking a reliable and hard-hitting round for use in regions where magazine rifles were less popular. Its introduction fit into the larger trend of developing powerful yet manageable cartridges for African and Indian big-game hunting, with the rimmed design ensuring positive extraction under the often harsh and unpredictable field conditions encountered abroad.

In terms of practical application, the .30 Super Flanged H&H stands out as a choice round for break-open firearms, particularly double rifles and combination guns. Its parentage provides it with performance characteristics similar to the rimless .30 Super, matching up well against other popular cartridges of the day in terms of velocities and terminal ballistics. Reloaders and enthusiasts appreciate its balance of power and controllability, making it a favored classic for those interested in traditional hunting methods and beautifully crafted double rifles. While it is less common than mainstream rimless cartridges today, the .30 Super Fl. H&H still garners respect among aficionados who value historical accuracy and the unique handling qualities of flanged cartridges in bespoke double rifles.

Traditionally, this cartridge was intended for large, non-dangerous game—deer, antelope, and certain African plains species. It delivers sufficient penetration and expansion with proper bullet selection, making it more than capable for classic “medium game” scenarios while still adaptable for use on lighter members of the dangerous game spectrum when paired with appropriate projectiles. In the early 20th century, it was considered an all-round cartridge for British sportsmen traveling to the colonies, particularly for fellows who preferred the quick second shot available in double rifles and the robust construction such weapons demanded from their ammunition.

Typical bullet weights for the .30 Super Flanged H&H range from 150 to 180 grains, often utilizing soft-nose or full metal jacket projectiles depending upon the intended quarry and local regulations. Modern handloaders can find or fabricate appropriate brass, with careful attention to maintaining the proper headspacing provided by the rimmed case design. The cartridge usually propels a 180 grain bullet at velocities approaching 2,700 fps, which was outstanding for its era, and remains effective today. Its moderate case taper and sturdy construction allow for reliable extraction, and its mild recoil by big game standards makes it pleasant to shoot in well-balanced rifles. For reloaders, maintaining the authenticity of their double rifles while achieving optimal performance from classic bullets and powders is part of the enduring appeal of the .30 Super Flanged H&H.
